JUMO Ex-i Isolating Switch Amplifier
Two-channel isolating switch amplifier for Ex applications
The intrinsically safe isolation switching amplifier ensures reliable, galvanic isolation and safe transmission of switching signals in Ex applications. It can be mounted in Ex zone 2 and the sensor can be operated in zone 0. The JUMO Ex-i isolating switching amplifier is ideal for JUMO NESOS float switches with 2 switch contacts and also supports NAMUR proximity sensors.
Two-wire or three-wire transmitter
The transmitters intended for industrial applications acquire the temperature with two-wire or three-wire connection. The continuous analog signal path allows for extremely quick output reaction times in the event of a temperature change (analog permanent measurement instead of digital sampling rate).

Two-wire transmitter
The two-wire transmitter acquires the temperature through an RTD temperature probe or a thermocouple. For RTD temperature probes, the probe can be connected in a two-wire circuit, three-wire circuit, or four-wire circuit. The dTRANS T01 Ex is designed for mounting in a potentially explosive area.
